9/13:Arizona Cardinals running back David Johnson will hope to improve on his solid performance last week in his Week 2 matchup against the Los Angeles Rams. Johnson has shown that he is virtually matchup proof; however, he needs to do better in the receiving game to generate consistent fantasy returns. The veteran running back should have no problem doing that in a game that the Cardinals are expected to play from behind, making him an RB1 as the team's main offensive threat.--Martin K - RotoBallerSource: Arizona Cardinals
